  • A dream came true. Battery problems may go away for good, due to graphene.

As I wrote almost 3 years ago about a new miracle material, and I was imagining how our lives might change, this is becoming more and more a reality.

An Australian researcher from Swinburne University presented at Fresh Science, a national program that helps early-career researchers find and share their stories of discovery, his new discovery. He is researching graphene capacities and applicability in real life, and he came up with a new super battery (actually, a super-capacitor) that can store as much energy per kilogram as a lithium battery but doesn’t have the drawbacks of a classic battery. Unlike modern batteries, Dr. Han Lin’s graphene supercapacitor charges very fast (in seconds), has a very long lifespan, meaning it can be charged and discharged millions of times without losing it’s proprieties and is eco-friendly.

“Our super-capacitor is extremely efficient, as it charges in a matter of seconds and holds a larger charge for a longer time because it consists of multiple sheets of graphene – creating a very large surface area on which to store energy.

“What’s more, charging and discharging won’t degrade the battery’s quality, so it can theoretically last for a lifetime – a unique property in the world of batteries.”

says researcher Dr Han Lin

Large scale production is easy.

Dr. Lin says large-scale production of the graphene that would be needed to produce these high-performance supercapacitors was once unachievable.

By using low-cost solution-based film synthesis techniques and a laser 3D printer, the researchers are able to produce graphene on a large scale at low cost.

In addition, the super-capacitors are very strong and flexible, and can therefore also be used to develop extremely flexible and thin batteries that could be built into wearable clothing and other personal accessories.

What would you say if you will have a smartphone that will stay charged for weeks and will recharge in seconds, or an electric car that will have a range of thousands of kilometers with a single charge and will recharge in minutes to its full capacity? All these things can be a reality sooner than you think.
